Hey. Any of your STs run on diesel? No? Well neither does my 2005 S1300! After 45 years of riding I finally put diesel in my tank. All of six gallons! It was at a Shell station in Leavenworth Kansas on my way home to Michigan. I pulled up to the pump and saw 87, 91 and expected 93 to be the next. Without even thinking I grabbed the 93 (diesel) and filled my tank. Boy was suppressed when it fired up and DIED. So. HOUrs later with a hefty tow bill and 2.7 hours at hind I was back on the road. If anyone is in the Kansas City area and needs service I would recommend Shawnee Honda to service your bike. Mike Everhart was able to fit me in and get me back on the road. I learned that I just had another Senior moment.
